- Q:i trying to make a solar panel. right now i dont have money to go and buy a copper sheet. so can i make it out of aluminum foil. if there is a way please tell me how. and what do i use for wires. i making this to charge batteries.
- Presumably you plan to create a focused parabolic reflector and have it oriented to heat the bottom of a pan. It will obviously need to be larger than the pan in order to gather sunlight outside of the pan's shadow, as well as gather and concentrate enough light onto the bottom of the pan to heat its contents. If you use black paint on the bottom of the pan, make sure it's high temperature paint (available at auto supply stores, often used to paint engine blocks and exhaust manifolds). Yes, a cover on the pan will make it hotter.
- Q:Can solar panels be installed on a shopping mall or retail complex?
- Yes, solar panels can be installed on a shopping mall or retail complex. Many commercial buildings, including shopping malls and retail complexes, have begun to incorporate solar panel installations as a way to reduce energy costs, promote sustainability, and demonstrate environmental leadership. The large rooftop spaces available on these buildings make them ideal candidates for solar panel installations, which can generate clean and renewable energy to power the complex. Additionally, solar panels can also be integrated into parking structures or canopies to further augment the energy production potential of the shopping mall or retail complex.
- Q:Can solar panels be damaged by birds or rodents?
- Yes, solar panels can be damaged by birds or rodents. Birds may build nests or perch on the panels, which can cause blockages or scratches. Rodents such as squirrels or rats may chew on the wires or insulation, leading to malfunctions or electrical issues. It is important to take preventive measures to protect solar panels from potential damage.
- Q:I want to build solar panels for my house.Dose anyone try okorder is this really work?
- |Its okorder /
- Q:discription how does solar panels save energy
- cool beans got it right. There is Solar electric which converts sunlight to electricity or Solar thermal that heats water or a transfer fluid. they both save energy in a big way. Solar electric or photovoltaic (PV) saves by off setting your electric bill directly. solar thermal saves by cutting the cost to heat your water and if properly sized can actually heat your entire house. This is done in a couple of ways but I won't go into that here.
- Q:Can solar panels be installed on historic buildings?
- Yes, solar panels can be installed on historic buildings. However, the installation process may require careful planning and consideration to ensure that the panels are discreetly integrated with the building's architecture and do not compromise its historical value. In some cases, solar panels may need to be installed in less visible areas or designed to resemble traditional building materials. Additionally, it is important to consult with preservation experts and local authorities to ensure compliance with any regulations or guidelines specific to historic buildings.
- Q:A solar panel facing the sun at noon in mid-summer receives more intensity of the light than when it is at horizontal. However, it can receives more total solar energy when it is at horizontal than when it is tilted during a long summer day. Regradless if it is shaded by building or trees. why is that so?
- i think it means that it will receive more (total for the whole day) when it is tilted to the most perpendicular to the sun. if you are on the northern /southern hemisphere, when the sun is not really directly above you. provided it doesnt automatically adjust
- Q:Basically I need a custom solar panel created. I won't go into detail but the dimensions need to be around 4''x2.5'' and be as thin as possible.
- Make okorder
- Q:Can solar panels be installed on a prison or correctional facility?
- Yes, solar panels can be installed on a prison or correctional facility. Installing solar panels can help reduce the facility's reliance on traditional energy sources and lower its carbon footprint. Additionally, it can save money on electricity costs in the long run. However, there may be certain security considerations and regulations that need to be addressed to ensure the panels do not pose any risks or vulnerabilities.
- Q:How do solar panels perform in extreme temperatures?
- Solar panels can still generate electricity in extreme temperatures, but their performance may be slightly affected. High temperatures can cause a decrease in efficiency, as the heat reduces the panel's ability to convert sunlight into electricity. However, modern solar panels are designed to withstand a wide range of temperatures, and their efficiency losses are generally minimal. In extremely cold temperatures, solar panels can actually perform slightly better due to the improved conductivity of the solar cells. Overall, while extreme temperatures can have a small impact on solar panel performance, they are still a reliable and efficient source of renewable energy in various weather conditions.
